Getting started

Currently we offer two different versions of sensenet ECM. We recommend version 7.0 for new projects as it is more lightweight and flexible.

sensenet ECM 7.0

A modern ECM platform that can be integrated into existing or new web applications. We modularized sensenet ECM so that you can install only the parts you need. Take a look at the currently published core components!

There is also a number of other built-in and 3rd party components and plugins that are built on this platform either by us or the community.

sensenet ECM 6.5

A feature-rich Enterprise CMS with predefined UI and building blocks: pages, portlets, action controls and more. Build your solution with almost no development effort.
